Add "Day of Week" on Sessions Page

I know that the sessions page is about to get a facelift with sortable/clickable/searchable columns, but in the meantime, it would really help if the "day of the week" could be added to these two pages:

Sessions in a day

So, 2025-11-03 would be 2025-11-03 (Monday)

Reservations in a session

So, 2025-09-11 4:00:00 (PDT) ICCS 008 would be 2025-09-11 (Tues) 4:00:00 (PDT) ICCS 008
